Abstract: 【Objective】 To monitor and protect the biodiversity of seabuckthorn woods, maintain its green and healthy development in Altay area. 【Methods】 In this study, the species and quantity of insects in seabuckthorn woods in Burqin county were investigated by the method of net trapping, and the temporal dynamics were analyzed by using biodiversity index. 【Results】 A total of 70 species, 61 families, 11 orders, and pests were 33 families, 7 orders, 35 species, 22 species, 15 families, 7 orders natural enemies were found in seabuckthorn woods. Neutral insects belonged to 4 orders, 13 families and 13 species. The number of family species and abundance of insects in seabuckthorn woods varied with time. 【Conclusion】 The main pest in seabuckthorn woods in Burqin county is Rhagoletis batava Hering, whose main natural enemy insect is Ichneumonidae, mainly including Sarcophagidae, Formicidae. The insect here is rich in species with large number and high richness and high diversity index, and Rhagoletis batava Hering can directly harm the fruit Hippophae rhamnoides, so it should be controlled to certain extent.
